To aZZ whom it may concern:

Be it known that we, ANTON SPONAR VON BLINSDORF and CARL ADLER, subjects of the Emperor of Austria-I-lungary, residing at Ba- 5 den, near the city of Vienna, in the Province of Lower Austria, in the Empire of Austria- Hungary, have invented certain new and use ful Improvements in Apparatus for Signaling and Stopping Trains on Railways, (for which I 0 we have obtained Letters Patent in Great Britain, dated April 2, 1889, No. 5,632; inFrance, dated April 8, 1889, No. 197,302; in Belgium, dated April 8, 1889, No. 85,748; in Germany, dated April 5, 1889, No. 49,022, and in Austria- Hungary, dated October 7, 1889, No. 12,043 and No. 51,342,) of which the following is a specification.

Our invention relates to improvements in signaling apparatus for railways; and it con sists in arranging in the tracks of a railway system a suitable apparatus operated from the signal-box and actuating either the alarmbell, the steanrwhistle, the brake, the steamvalve, or the reversinggear of an engine passingover such apparatus, so as to stop the former forthwith.

In the accompanying drawings, Figure 1 represents a vertical View of the apparatus in combination with a part of the engine. Figs.

0 2 and 3 represent two vertical cross-sections of the casing in a larger scale. Fig. 3 is a section on the line 00' as of Fig. 2.

In carrying our invention into practice we sink in the ground between the rails or support by cross-bars 2ft, fixed to the sleepers, a casing r, slotted at the top and containing a vertical jointed and collapsible rod or bar "a, which is pivoted at its lower end at '0 and connected to a second rod 1:, adapted to be turned about the trunnion 7". Both rods u 40 and e are jointed at o to a horizontal rod 6, extending through the side of the casing arid connected to the signal-box by means of suitable cranks. This bar a when in an erect position projects above the rails and comes into 5 contact as an engineis passing over the same with suitable spring-levers g 9 attached in any suitable part of the under side of the said engine, and connected by suitable levers or other mechanism to the bell or other part of the engine which is required to operate.

To claim as our invention and desire to secure by Letters Patent A signaling apparatus for railways, consisting of a casing containing a vertical jointed and collapsible bar a, hinged to another bar o, adapted to be turned about a trunnion 1, both rods jointed to a horizontal rod extending through the side of the casing and connected to the signal-box by means of suitable 6o cranks, in combination with spring-levers attached to any suitable part of the under side of the engine and connected by suitable mechanisms to the hell or other part of the engine which is required to operate, substantially as set forth, and for the purpose specified.

In testimony whereof we have signed this specification in presence of two subscribing witnesses.
